Marginal/unclear security implications, the redirects are fully under control of
the puppet masters and the advisory states this CVE would be similar to CVE-2018-1000007,
but CVE is for curl, which obviously has different scope being a library. Plus, all
reasonably secure installations use client auth on the agents
Previous client code in lib/puppet/network/http/connection.rb also vulnerable
